Definitions

  • This invention relates to a method for preparing brewed coffee utilizing an infusion coffee bag containing roasted and ground coffee.
  • the infusion coffee bag is immersed in water and microwave heated to produce a high quality coffee brew in a short period of time.
  • One method of decreasing the time to produce a coffee beverage is to increase the porosity of the infusion coffee bag.
  • the increase in porosity also permits increased amounts of coffee grounds to escape thereby producing accumulations of sediment in the cup.
  • US 4,386,109 (equivalent to DE-A-3,206,803) pertains to an espresso coffee maker for use in a microwave oven. Water is stored in a microwave- transparent reservoir container and is heated by microwave energy to a temperature such that the resulting pressure forces steam and hot water out of the reservoir container through to coffee grounds in an adjacent pot.
  • the invention provides a method for preparing a coffee brew which comprises:
  • the invention provides a coffee-brewing arrangement comprising an infusion coffee bag immersed into a container of water at a temperature in the range 10°C (50°F) to 65.6°C (150°F) and microwave heating apparatus arranged to heat said water.
  • water having a temperature from about 10°C (50°F) to about 65.6°C (150°F) and preferably from about 15.6°C (60°F) to about 23.9°C (75°F), is first added to a container such as a cup or a pot for example.
  • the water is suitably cold tap water or water at room temperature, however, hot tap water or preheated water below 65.6°C (150°F) may be employed.
  • the water is preferably added in an amount of at least one coffee serving size which is at least 113.4 g (4 oz.) and more preferably at least 170.1 g (6oz.). More than one serving size amounts of water may be added to the container.
  • an infusion coffee bag comprised of roasted and ground coffee packaged in a filtered paper infusion bag.
  • the roasted and ground coffee has an average particle size from about 400 mesh to about 1100 mesh.
  • the bag material may for example be comprised of a thin porous filter paper preferably coated on at least a portion of one side with a thermoplastic material which will become adhesive upon being subject to heat and pressure, thus enabling formation of the bag by a heat sealing operation.
  • Suitable tea bag material will have a porosity of from about 91.4 to about 198.1 m 3 per minute per square metre (300 to 650 ft 3 per minute per square foot) at 124.6 Nm- 2 (0.5 inches water pressure).
  • the roasted and ground coffee material used in this invention may be any single variety of coffee but it is usually a blend of different varieties.
  • the blend may be formulated either before or after roasting or grinding.
  • the coffee may be decaffeinated or undecaffeinated.
  • the amount of coffee in the bag must be suitable for producing a serving size of coffee which is generally from about 5 gms to about 15 gms.
  • the container with water and the immersed infusion coffee bag is then placed into a microwave heater.
  • Most microwave ovens employed for the ordinary household use operate at 2,450 megahertz and at a wavelength of 12.2 cm. Other frequencies may be used for microwave cooking, for example, 915 megaherzt with a wavelength of 33 cm is also commonly employed.
  • the amount of power employed for household cooking may be as little as 400 watts and as high as 2,000 watts for some catering ovens. In general, however, most domestic microwave ovens are in the range of 600 to 1,000 watts at the frequency of 2,450 megahertz.
  • the container of water with the immersed infusion coffee bag is placed into the microwave oven it is heated to a temperature effective to produce a coffee brew.
  • this temperature is in the range from about 71.1°C (160°F) to about 98.9°C (210°F) and preferably is in the range from about 76.7°C (170°F) to about 93.3°C (200°F).
  • the heating time is usually less than 2 minutes and often less than 1 1/2 minutes. When multiple servings are prepared, a somewhat longer time is needed depending on the amount of servings.
  • Example 6 gms of roasted and ground coffee in an infusion bag were placed in a cup containing 150.25 g (5.3 ozs.) of water having a temperature of 20°C (68°F).
  • the roasted and ground coffee had an average particle size of about 480 mesh and the infusion bag had a porosity of about 129.8 m 3 per minute per square metre (426 cubic feet per minute of air per square foot) at 126.4 Nm- 2 (0.5 inches of water).
  • the cup was placed on a gas stove and heated by flame to a temperature of 82.2°C (180°F) in 2 minutes. After heating, the cup was removed from the heat and the coffee bag was dunked three times and then squeezed into the cup. It was determined that the coffee brew had soluble solids of 0.51 weight percent. It was determined that the final brew color was extremely light and the coffee had very thin flavor.
  • This example is also presented as a Control.
  • a coffee bag similar to that employed in Control A was placed in a cup container. Boiling water at a temperature of 100°C (212°F) was added to the cup containing the coffee bag. The temperature of the cup after 30 seconds was 82.2°C (180°F). The coffee bag was dunked three times at the start of brewing, three times after one minute and three times at the end of two minutes. At the end of two minutes the bag was removed and squeezed into the brew. The soluble solids of the brew was determined to be 0.63 weight percent. While the color of this coffee was acceptable, it was determined that the cup strength of the coffee was weak and lacking total coffee character.
  • each coffee bag was immersed into preheated water, microwaved heated to 82.2°C (180°F), dunked three times and then squeezed into the cup.
  • the first cup of water was preheated to 62.2°C (144°F) and then microwave heated for about 44 seconds.
  • a cup of coffee with good flavor was produced.
  • the second cup of water was preheated to 65.6°C (150°F) and then microwave heated for about 35 seconds.
  • a cup of coffee with good flavor was prepared.
  • the third cup of water was preheated to 68.3°C (155°F) and the microwave heated for about 28 seconds. A thin brew not acceptable as coffee was produced.
